ACS402-5SB4

Overview

The ACS402-5SB4 is a quad AC line switch array in a DIP-20 package. It integrates four bi-directional switches with a repetitive peak off-state voltage of 500V and a clamping voltage of 600V. Each switch supports an RMS on-state current of 0.2A, totaling 0.4A for the array. The device features a gate triggering current of less than 10mA and withstands non-repetitive surge currents up to 5.5A. Operating junction temperature ranges from -30°C to +125°C.

Feature Summary

• Integrates four high-voltage bidirectional AC switches within a single package
• Includes internal high-voltage clamping structure for absorbing inductive turn-off energy
• Features integrated gate level shifter driver for direct microcontroller interfacing
• Eliminates need for external overvoltage protection devices

Applications

• Static switching in appliance control systems
• Driving low power inductive loads such as solenoids, valves, and relays
• Controlling micro-motors, pumps, fans, and door locks
• Switching low power lamp bulbs

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm the specific ordering suffix matches the required DIP-20 tube packaging configuration. Review the datasheet revision history for any updates to electrical characteristics or thermal resistance values before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring multiple isolated AC loads controlled by a digital interface. Ensure the load current does not exceed 0.2A per channel. Verify that the system can accommodate the negative gate trigger current requirement. Consider the thermal dissipation limits if operating at elevated ambient temperatures or with all channels active simultaneously.

Part Context

This part belongs to the ASD (AC Switch Driver) family developed by STMicroelectronics. It utilizes proprietary technology to combine switching and driving functions.
